NITED STATES MARY F. BURROUGHS, OF MARSHALL, MISSOURI.

SEWING-MACHINE SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 606,443, dated June 28,1898.

Application filed May 11, 1397- Serial No. 636,028. (No model.)

To all whmn it may concern:

Be it known that I, MARY F. BURROUGHS, of Marshall, in the county ofSaline and State of Missouri, have invented certain new and usefulImprovements in Sewing Machine Shuttles; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same. i

This invention relates to improvements in sewing-machine shuttles; andthe same has for its object to provide an improved shuttle in which thespool of thread may be placed directly without the necessity of windingthe cotton therefrom upon a bobbin, as in the ordinary construction ofshuttle.

The invention consists in the details of construction hereinafter fullydescribed and claimed, and illustrated in the accompanying drawings, inwhich- Figure 1 is a perspective View of my improved shuttle in positionwithin the shuttlecarrier provided therefor. Fig. 2 is a perspectiveview of the shuttle-carrier with the shuttle removed therefrom. Fig. 3is aview of the shuttle with the door opened to show the spool inposition therein. Fig. sis-an end view.

1 indicates a shuttle-carrier, one end of the same turned at rightangles to form the back wall, against which the end of the shuttle isadapted toabut, and having a portion of its side wall also turned up toform a guide for the shuttle. The forward end of the carrier is turnedup at 2 to be out of the way of the loop of thread formed by thedescending nee- The turned-up end 20f the case also assists in holdingthe shuttle in proper posi-. tion therein by engaging the front portionthereof, and the said case as an entirety is adapted to be carried by areciprocating arm coacting with a raceway, all of which is well known inthe art to which this invention appertains.

The shuttle consists of a circular casing 3, which is pointed at itsforward end, as illustrated at 4, and has its rear end 5 hinged thereto,as illustrated at 6. A door 7 is pro vided, which is'hinged to thecasing at its lower end and adapted to be secured at its upper end bythe latch 8, carried by the casing. \Vhen this dooris opened, asillustrated in Fig. 3, accessmay be had to the interior of theshuttle-casing through the side and top wall thereof for the purpose ofinserting the spool 9. A screw 10 passes through the outer wall of thecasing and engages one of the ends of the spool, whereby the tension isregulated as desired.

The door of the casin g is provided with the usual V-shaped slot 11,through which the thread is passed, and upon the outer surface of thedoor is a spring-guide 12, having its central portion looped, asillustrated at 13, said guide being for the purpose of receiving thethread after the same has been passed through the slot, the threadworking beneath the looped portion thereof.

In operation the door is opened and the spool inserted within thecasing, the hinged end wall of the same -greatly facilitating theinsertion of the spool, and the thread is in sorted through the V-shapedslot. The door is then closed and secured by the latch and the threadplaced beneath the guide provided therefor. The shuttle is then insertedin the casing, the end wall of said casing or holder preventing themovement of the hinged end of the shuttle. The thread in then passedbeneath the hook upon the casing or holder, which serves to guide thesame.

From the above description it will be seen ready for sewing without thenecessity of removing the spool or shuttle. This is a great advantage inthat time and labor are saved the operator.

Having thus fully described the invention, what is claimed as new, anddesired 'to be secured by Letters Patent, is

1. A shuttle, comprising a casing rounded threaded in the door, and themachine is again to conform to the contour of the spool of thread, oneof the end walls of the casing being hinged thereto, the opposite endbeing pointed, a door hinged to the casing by means of which access maybe obtained to the interior of the casing for inserting the spool ofthread therein, means for securing the said door in a closed position,said door being provided with a slot through which the thread is adaptedto be passed, a guide upon the exterior of the door for holding andguiding the thread, and a screw adapted to be passed through the casingand bear at its end upon the spool to regulate its rotation,substantially as set forth.

2. The combination of a shuttle-carrierprovided with a guiding side walland an end wall, a shuttle comprising a casing having its end wallhinged thereto and its opposite end pointed and adapted to be positionedwithin the said shuttle-carrier, a door for the shuttle by means ofwhich access is obtained to the interior thereof, a latch whereby saiddoor is secured in closed position,ia springguide upon the door fordirecting the thread from the said shuttle, and a tension device bymeans of which the rotation of the spool of thread is regulated,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
